Hi! I'm trying to build https://github.com/hyperledger/iroha-java manually with Gradle (tried with Guix but I'm stuck), and I get the following error: --8<---------------cut here---------------start------------->8--- Execution failed for task ':client:compileJava'. Could not find tools.jar. --8<---------------cut here---------------end--------------->8--- Then it suggests that the Java installation might be wrong. I tried with icedtea 3.7.0, openjdk 9 and openjdk 12, to no avail. Are our JDK packages wrong missing some jars? -- Pierre Neidhardt https://ambrevar.xyz/
